Rundle Street murder accused's identity suppressed

A man, 24, has faced an Adelaide court accused of murdering another in a city street in the early hours of Sunday.

The Magistrates Court has suppressed details of the accused man's identity.

Police prosecutor Brevet Sergeant Sharon Baker says a witness saw the victim speaking with a group of men including the accused, about 2:30am on Sunday at the corner of Rundle Street and Synagogue Place.

It is alleged the accused then punched the victim, 44, who fell to the ground and later died in hospital from serious head injuries.

"[The witness] observed the victim falling backwards with the accused moving his shoulder towards the victim and his left arm extended," the court was told.

The prosecutor says a number of witnesses have been spoken with.

"Witnesses have implicated the accused with having struck the victim," she said.

The alleged offender turned himself in to police on Monday.

CCTV to be checked

Defence lawyer Michael Woods has told the court the man who died earlier had been behaving poorly inside Apple Nightclub.

"The deceased in this matter had been behaving incredibly bad earlier in the evening (of Saturday) and the CCTV footage we are confident will support that," he said.

"It's not a situation of someone out in the city looking for gratuitous violence ... it's not that sort of case.

"It's very unlikely to be that charge (murder) at the end of the day."
